This present disclosure is a continuation of U.S. application Ser. No. 14/952,458, filed on Nov. 25, 2015, which claims the benefit of and the priority from U.S. Provisional Patent Application No. 62/195,027, filed Jul. 21, 2015, each of which is incorporated by reference in its entirety.

BACKGROUND OF THE INVENTION

Current network plug technology limits the amount of data that can be transmitted from a cable connected to one portion of a plug to a device connected to a second portion of the plug. As data communication speeds increase, the need to provide a properly grounded connection between two points becomes critical.

Currently, grounding of network connections requires manual manipulation of a grounding wire to a plug. Often, this manual manipulation results in an improper ground connection that may result in loss of data transmission due to transient signals. Further, manual manipulation of the plug requires additional man hours to terminate and test each connection, thereby increasing costs of installation of network connection points.

A need exists for a plug that creates a proper ground connection without manual manipulation of the plug.

A portion of the solder pad 114 between the opening 110 and the via 108 is substantially triangular in shape. An area 116 on the substrate 102 between the opening 110 and the solder pad 14 is empty to allow for movement when a wire is inserted into the IDC 112. FIG. 1C depicts a side view of the plug 100 including an IDC 112 installed in a via 108. The IDC 112 is positioned on the solder pad 114 and in the via 108 such that the IDC 112 is parallel with the top surface of the substrate. By inserting the IDC 112 into the via and above the solder pad 114, the capacitance of the IDC 112 is reduced.

FIG. 2 depicts a top view of a bottom layer of a multi-layer high speed plug. The bottom layer includes 200 includes a first group of vias 202 and a second set of vias 204 with half of the first group of vias are connected by a trace 206 to a corresponding second via 204, and a grounding plane 208 and a plurality of grounding vias 210.

When assembled, the first vias 202 and second vias 204 extend through each layer of the multi-layer plug. The grounding vias 208 extend through each layer of the multi-layer plug electrically connecting the grounding planes in each layer.

FIG. 8 depicts one embodiment of a plug 800. A first group of vias 804 is formed through a substrate 802 with each first via 804 being connected to a second via (not shown) by a trace (not shown). Grounding strips 806 are formed on the sides of the substrate 802 between the first group of vias 804 and the second group of vias (not shown). The grounding strips 806 are electrically connected to at least one grounding plane in the substrate 802.

Each side of the plug housing 1700 includes wire openings 1702 with each wire opening 1704 being aligned to an opening 1504 on the substrate. Each wire opening 1702 is sized to accommodate a solid core or stranded wire. In one embodiment, the wire is a #24 wire. In another embodiment, the wire is a #22 wire. The plug can accept any number of wires based on the size and density of the substrate. In one embodiment, the substrate accepts a single pair of wires. In another embodiment, the substrate accepts twelve pairs of wires. When a wire (not shown) is inserted into the wire opening 1702 the wire is guided by the wire opening 1702 into a securing unit 1506 positioned in the opening 1502 corresponding to the wire opening 1702 such that the wire engages the securing unit 1506 to secure the wire in the opening 1502 and to provide an electrical connection between the wire and the connection pad 604 via the securing unit 1506.

By exposing the grounding strips 1512 through the plug housing 1700, the plug can be grounded to a high speed communication jack without any additional crimping or wiring thereby increasing the reliability of the ground connection, and reducing the labor required to install and ground the plug. The plug housing 1700 includes a plurality of pin openings 1706 one the end of the plug hosing 1700 opposite the substrate 1502 with each pin housing aligning with a pin 1508 on the substrate 1502 when the substrate 1502 is inserted into the plug housing 1700.

FIG. 18 depicts a view of the substrate inserted into the plug housing.

Securing units 1506 include pins 1800 on one end of the securing unit 1506 with each pin 1800 being sized to engage a corresponding via 1608. Each securing unit 1506 is inserted into a respective opening 1502 by inserting the pin 1800 into the via 1608 and positioning the back portion of the securing unit 1506 parallel to the surface of the substrate 1502 such that the securing unit 1506 covers the connection pad 1614. Traces 1602 and 1612 extend from each connection pad 1614 to a corresponding pin 1508 at the opposite end of the substrate 1502. By positioning traces 1602 and 1612 on both on the top surface and bottom surface of the substrate 1502, the signals transferred on the traces are better isolated thereby reducing interference. Grounding surfaces 1614 are positioned on opposite sides of the substrate 1502 near the pins 1508 and provide a grounding connection between the connection jack and the plug.
